Then put this page aside a moment, leave the ignition and motor off, then call 0333 366 0103. In Street End, finding it before the engine runs usually leaves draining and a thorough flush on the spot. The rest of this page explains why it occurs and how to ensure it doesn't — useful if you're reading before it has happened. ## AdBlue in a diesel motor, and its separate tank Not one fluid but two: that's how many newer diesels near Street End and Woodhouse Green run, with diesel for the motor. Stored in a tank of its own, AdBlue is fed into the exhaust stream to clean it. Separate tanks, separate fillers. Other motors put the AdBlue filler in your boot or under the bonnet; a lot of others place the two side by side under one flap. The diesel side is fuelled at the pump all the time. The AdBlue side is fuelled far less regularly, usually from a bottle, and normally by somebody who has to stop and think where it goes. It's in the gap that the slip happens. ## AdBlue in your diesel tank in Street End: how it takes place Three things tend to line up, and carelessness is rarely one of them. Hurry follows from the warning. The vehicle warns you as AdBlue runs low, and a dry tank puts the vehicle into limp mode — so the top-up happens in a rush, before work on a drive off Glenmore Drive, or on the way home in the car park at Street Bridge Inn. Then the vehicle is new. A hire car, a new car or a company car puts the fillers where your last one did not, and the hand gets to for the cap it would have used on the old one. And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, and so nothing stops the tip once it has started. It's a few seconds, be it out in Holt Lane End or bang in the heart of Street End. ## The AdBlue filler and your diesel filler: telling them apart Be it a Street End forecourt or a drive out in Lime Side, take a few seconds over these before any goes in. - The cap. The AdBlue cap is commonly blue, or marked "AdBlue". Your diesel cap normally is not. Read it instead of going by position. - Many motors give AdBlue the smaller filler of the two. - Lift the filler flap and check for a label — many vehicles mark which belongs in which filler just there. - In the boot or under the bonnet: that is where the filler sits if it is not by the diesel cap, and the handbook says which. - The previous driver will know. Check as you pick up a rental or company car — from Moston's car park, say — not when the light comes on. ## Keeping AdBlue out of the diesel tank when you top up A routine for the day the light comes on, wherever across Greater Manchester that is. - Park then switch off. Not on a slope, not with the engine running, and not in a rush on the side of Westminster Road. - Find the AdBlue filler, read the cap, and say the name "AdBlue" out loud as you unscrew it. It seems silly. It does the trick. - The diesel cap remains on. When both sit under a flap, confirm it's shut before lifting the bottle. - Gently is best, through the bottle's own spout, till it's full or the bottle is empty. - Close the cap, and check again — making sure the diesel filler remained closed the whole time. Only then, start the vehicle. Spot at step two or three that it has already gone into the diesel side? So stop right there. Don't go on to step five. ## Put AdBlue in the diesel tank in Street End already? Do not start your motor: that's how the short order of things begins. Don't switch your ignition on; on many diesels that alone runs the fuel pump. Filling up with diesel won't weaken it: rather than mixing, AdBlue drops to the bottom of that tank, right where fuel is taken from. Ask the staff to help roll the vehicle clear of the petrol pump if you're on a forecourt — the EG On the Move, the Gulf or somewhere else. If you're on your own driveway around Street End, leave it where it sits. Where your motor has been run by now, pull over safely and switch the car off. On the M60, under a mile from Street End, that means the next exit. Roughly how far did it go? Crossing Street End is less work than a trip of under 5 miles towards Manchester, and so say. ## What happens when our technicians get there in Street End Wherever the car came to rest, be it outside Higher Failsworth Primary School, near Hollinwood Cricket, Bowls and Football Club or on your own drive, the van comes to it. What fluid went in, the quantity, and if it ran: we ask since the replies set the work and price. You hear that quote by phone, before anyone sets off. After that: draining, then a full flush of the whole system. With AdBlue that counts more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, so it doesn't wash out on its own. Testing is at the end: before that, fresh diesel goes in, and your filter is cleaned or replaced if necessary. The motor is fired up next and tested to confirm it runs smoothly, all before we leave. Unrun vehicles mostly mean a half-hour visit after the moment we arrive. The equipment is fine on a busy filling station, and hushed enough for a residential street after dark. No money in advance; you settle up that day. Afterwards, a VAT invoice and the report from the engineer are handed to you for the insurer. It is worth checking your insurance as the van travels to you: misfuelling cover is included with plenty of policies. ## About Street End and where it is Street End is a suburban area in Greater Manchester, situated approximately 4.8 miles east of Manchester city centre.
